T0 all whom t may concern.'

Be it known that-1, JOHN C.- ENGLISH, a citizen of the United States, and a resident of Camden, State of New Jersey, have invented certain new and useful 1mprove. ments in Talking-Machines, of which the following is a full, complete, and exact disclosure. p

The main objects of this invention areto provide an improved talking machine of simple, compact, durable and efiicient construction; to provide in a talking machine an improved mounting for al swingingvsound box arm, and improved sound amplifying means; and to provide other improvements as will appear hereinafter.

In the accompanying drawings Figure 1 is a fragmentary side elevation partly in av vertical section of a talking machine constructed in accordance with my invention, and Fig. 2 is a rear end elevation of the same.

Referring to the drawings, one embodiment of this invention comprises a cabinet having a body or main portion 1 mountedl upon a hollow base 2. Upon the top of the body l is mounted a horizontal turntable 3 for supporting the usual sound record 4. r[he body of the cabinet contains the usual l motor or actuating mechanism (not shown) for rotating the turntable, and the base of the cabinet contains amplifying means described hereinafter. The body of the cabi?. net is separated from the base by suitable flooring which divides the cabinet into two.. entirely separate compartments, to prevent any noise from the actuating mechanism of the turntable from being communicated to the amplifying means.

For supporting sound reproducing means and for sound conducting and sound amplifying purposes there extends outside of the rear wall of the body lof the cabinet a stationary, rigid bracket 5 which has integral therewith a Hat base plate 6 resting against the outer wall of the rear side of the cabinet and projecting laterally upon each side of the main portion of the bracket. The bracket is rigidly clamped to the cabinet by bolts or thumb screws 7 which extend through holes in the base plate and through the rear side of the cabinet and are held in position by nuts 8 upon the inside of the cabinet.

The bracket 5 is provided with a hollow, vertical portion, which extends upwardly and downwardly from the central portion of the bracket and forms a Sound conveying passage 5. The upper end of this vertical part of the bracket is substantially circular 1n transverse section, and terminates about on a level with the turntable of the machine in a circular socket 9, adapted `to receive the larger end of a hollow tapering tone arm 10, which carries at its smaller free end a sound box l1 arranged to cooperate with the record 4. The main part of the taper arm 10 extends horizontally, and terminates at its large end in a quarter turn, which brings the lower end of the arm into the socket of the bracket heretofore described. Y

The taper arm is rigidly mounted upon a spmdle 12, extending vertically through the larger end of the arm through a lug 13 upon the upper side of the downwardly curved part of the arm, and through a bridge 14 extending diametrically 'across the lower `end of the arm. The spindle 12 is rotatably mounted at its lower end in a bridge l5 ffixed diametrically across the upper end of the .opening in the hollow bracket, and the upper end of the spindle is reduced in size to form a pintle 16, fitting into a vertical plunger 17, which is slidably carried in a socket 18 in the under side of the upper end of a solid arm 19, the lower end of which is rigidly secured to the upper end of the hollow bracket by means of a bolt 20. A spiral spring 21 is seated in the socket 18 above the upper end of the plunger, and presses the plunger downwardly, and holds it in engagement with the spindle 12. By this construction, when it is desired to remove the taper arm fromits supporting bracket, the larger end of the taper arm is lifted 'upward'ly, bringing the spindle upwardly against the vielding plunger, thus releasing the spindle from the bridge 15, and the arm may be lifted out of its socket.

The vertical portion of the hollow bracket gradually changes in its transverse sectional contour and gradually increases in transverse sectional area as it extends downwardly from the circular formation of the upper end of the bracket to an oblong, substantially rectangular formation at the lower end of the bracket. The diameter of the passage-way in the bracket, measured longitudinally of the machine, gradually decreases from thetop of the bracket downwardly, and measured transversely of the of the bracket downwardly, so that the side elevation (Fig. '1) presents the vertical portion of the bracket as converging downwardly, while the rear elevation (Fig. 2) presents the vertical portion of the bracket as diverging downwardly.

The lower end of the vertical portion of the bracket is given a quarter turn inwardly, and extends through an'aperture 22 in the rear side of the base of the machine, without coming in contact with the base, and terminates just within the base in a socket 23, adapted to receive the inner end of the sound amplifying device, which is rigidly secured within the socket, and supported entirely by the hollow sound conveying bracket.

The amplifying device-comprises upper and lower resonant fiat sound boards 24 and vertical sound boards 25, secured together' at their edges to form an outwardly diverging passage-way, the inner edges of these sound boards being secured within the .socket at the lower en'd of the hollow bracket heretofore described,and the inner end of the passage-way between the sound boards communicating with the passage-way through the bracket. The outer edges of the boards terminate within the base of the machine, and are spaced a small distance from the inner side of the door 26 in the front side of the base, which extends over the outerend of the passage-way between the sound boards. The passage-way between the sound boards is thus normally in communication with the space in the base surrounding the amplifier, the passage-way, however, between the interior of' the amplifienand the interior of the base being considerably less in area than the area of the outer end of the passage between the boards. Bv means of' the doors 26 the passage-way between the boards and the chamber of the base surrounding the boards may be put in direct communication with the air surrounding the cabinet by opening the doors to get the full efi'ect of the reproduction, or the doors may be closed or partly clcsed and the volume of the sound accordingly diminished.

Although only a single form has been illustrated in which this invention may be embodied, the invention obviously is not limited to this particular construction, but may be applied in other forms without departing from the spirit of the invention or the scope of the appended claims.
